I This invention relates to an apparatus for the commercial preparation ofcofiee, cup by cu and so constructed and operated that the co co can be made practically continuously.

v 5 It is'an object of the invention to rovide a device which is operated electri'ca ly and which embodies various means and devices whereby the coflee can be prepared expedi tiousl with a minimum of power and manual labor and at the same time so expeditiously that a large number of people can be supplied with cofiee in a minimum of time.

It is also a feature of this invention to provide the apparatus with a percolator having a rotating device cooperating therewith which is designed to provide suflicient coffee powder to the percolator to diffuse hot water and steam through said owder and to discharge the spent coffee a ter a cup of cofiee so has been prepared.

It is also a further object of the invention to provide adevice having a semi-automatic percolator, a manually operated percolator and an immersion heater with means where- 35 by hot water and steam may be directed to an one of these instrumentalities at will.

it is also a feature of the invention to provide a construction in which all the various elements are compactly and efliciently combined so as to occupy the smallest possible ace. 1 a With these and other objects in view-which will become apparent as the description pro-- ceeds, the invention consists in the combma- 35 'tion and arrangement of parts hereinafter described, claimed in the claim and shown in the drawings, in which Figure 1 is a front elevation view of the the section line IV-IV of Figure 3,

. Figure 5 is a sectional view taken upon the section line V-V of Figure 3 and Figure 6 is aplan view of the revolving feature with cooperating actuating mechanism used in the Refer to the drawings, in which like reference c aracters are used throughout to ind cate like parts in the various views, the apparatus consists of a frame which is preferably metallic having a base 1 which is designed to be supported upon a counter desk or shelf, The frame has a cylindrical body 2 having side apertures designed to be removably covered by the bolt plates 3 and 4. The top of the frame is enclosed by a dome 5.

General aase'ntblge Extending from'the outside of the body 2 are the cup supports 8, 9 and 10 arranged in.

tor 11 of the ordinary type which is designed to be manually fed with coffee powder. Arranged in cooperating position with thecup sup ort 8 is the semi-automatic. er-' colator 12 s own more particularly in ig- V ures 2 to 6, and arranged in cooperating relatlon with the cup support 10 is a coil pipe 13 for heating by immersion. The support 10, is eguipped with a hollow pipe rotatableupon the pivot 14 in order to allow the discharge of condensation water from the end pipe 15 upon the coil pipe 13,

' The percolators Of the two percolators 11 and 12, the first need not be particularly described since it is I of'a common and ordinary construction well.

known in the art. However, in regard to percolator 12, this is of an essentially novel construction and will be described in detail. Reference is made particularly to the showing in Figures 2 to 6 inclusively.

The supporting arm secured to the outside body member 2 has at the lower end thereof three divergent members 31 to which is secured a lower plate by means of the bolts 49. The plate 50 has fastened to it at its upper surface a second plate 51 by means of the bolts 49 previously mentioned and also 1 the bolts 52. The plates 50 and 51 are spaced from one another to form' a chamber in which semi-automatic percolator, is located a third plate 53 constituting the 1 feeder plate which is rotatable upon a central pivot member 54.

The upper plate 51 is provided with three circular apertures therein s aced 120 from one another and designate 55, 56 and 57. The apertures 55,56 and 57 have circular vertical flanges surrounding the same.-

A hop or 56 is located in the aperture 55 and the 0 er is designed tocontain coflee powder an 1s connected to the plate 51 by" a threaded collar 59. The aperture 56 has therein a union piece or connection which in turn is connected with the pipe 28 through which hot water and steam is supplied. A washer 61 is located at the lower surface of the union iece or connection so as to ensure a water tig t joint.

A cover plate 62 covers the aperture 57 and the cover plate is apertured centrally thereof to permit passage of a rod 63 carrying at its end below the cover plate 62 a piston 64. which is designed to remove spent codee grounds.

The rotatable plate 53 is rovided with three apertures 65 aligned wit the apertures 55, 56 and 57 of the plate 51. A bushing 66 is located in each of the apertures 65 in the plate 53 and each bushing is provided with a washer 67 located between the bushing 66 and l the lower plate 56 and which is urged into tight contact therewith by a coil spring 66 surrounding the bushing 66 and reacting against the plate 56 and a flange provided Y upon each hushing 66.

, The plate 56 is provided with two aper tures 69 and 7 6 which are aligned res cctive- I ly with the apertures 56 and 57 of t .e plate 51. A strainer 71;- is located over the sper ture 69 and directly below the same is a per colator 62'. The percolator 62' is secured in position by means of a nut 72 which has se= cured thereto a handle 7 3. A collar 7 5 ertends downwardly from the a erture 69 and may be either integral with t e plate 56 or secured thereto in any desired manner. The collar 75 is provided with a thread which cooperates with the nut 72.

The operation of the turret percolator is as follows: g

The plate 53 with the bushing 66 therein is rotated so as to bring one of the bushings 66 below the hopper 58 and cofiee powder Wlll be supplied from the hopper 58 so as to fill the I bushing 66 directly thereunder. By then re tatin the plate 56 120 the filled bushing 66 will e brought into position directly over the strainer 71 which covers theaperture 69 in the plate 50. The handle 23 located at the front of the apparatus is then turned, so

as to operate the valve 22 to connect the pipe 28 leading to the turret percolator with the water heater and water and steam will be conveyed to the coffee powder located in the v bushing 66 ositioned above the vstrainer 71. A deflector 1s preferably secured to the termination of the pipe 28 within the coupling neoasie member to scatter the hot water and steam over the entire surface of the coffee owder positioned above the strainer 71. T e difusion having been made the cofiee beverage will flow through the pipe 76 upon the per-- colator 62 into a cup placedupon the support 8. After the beverage has been drained the plate 53 is again rotated through an arc of 120 and the bushing 66 having the spent codes powder therein will be brought into alignment with the aperture upon the plate 50 and by reciprocating downwardly the piston plate 641:, the exhausted cofiee powder is discharged into a pipe 77. I

The operation of feeding and discharging the codes powder takes place automatically. lln the filling of the bushing 66 located. below the hopper 58 the force of gravity efiects the filling and the discharging of the spent codes powder is accomplished by rotating the screw nut 72.

lln order to accomplish the downward reciprocation of the piston plate 6d a lever 7 8 is provided pivoted at 7 9 to a member secured to the plate 51 186 removed from the aperture 57 The rod 63 is pivotally connected to the other end of the lever 7 8 and approximately at the center of the lever 7 8 a rod 82 passing through the aperture pivot 54 is pivoted at 81. The lower end of the rod 82 is provided with a slot 82 extending horizontally and this slot coo; crates with a helicoidal sector 83 lined upon t e screw nut 7 2. It will he noted that when the'screw nut 72 is unscrewed in order to release the plate 53 which hasheen previously clamped into position by screwing the-nut 72, the sector 83 will slide in the slot 82 and raise the rod 82; and thereby the piston 64} in order to clear the plate 53. when rotated. When the next charge of coii'ee powder is located in position over the percolator 62 and the screw nut 72 is retated in order to clamp the bushing 66 with its charge of codes powder in position, the sector carried by the nut 72 will lower the rod 82 and the piston plate 64 and thereby remove the codes powder which has been exhausted from the bushing 66 into the dis charge member 77.

In order to provide for the rotation oi plate 53 there are provided upon the plate erlpheral teeth 84 shown more perthree ticular y 111 Figure 6. The teeth are arran 76d 126 apart from one another and are desi ed to be successivel engaged by a rate et pawl 85 The paw 85 is positioned within the handle 86 which in turn is escured to a lever 87 which is also pivoted u on the pivot 54 beneath the plate 50. The rate et pawl is resilientl urged inwardly against the periphery of t e plate 53 b a coil spring 88 located inside of the handle member 86. The pawl 85 extends through a slot on formed between the plates 50 and 51. To rotate the plate 53 it is only necessary to operate the handle 85 through an arc of 120. The return spring 89 will return the lever 87 into engagement with a tooth 84 which is to be operated upon in order to secure the next I rotation of the plate 153. A buffer 90 is also provided to take up the shock of the return movement of the lever 87 to position.

If desired, a recorder to may be connected to the late 51 upon the turret percolator so I. as to actuated upon each oscillation of the handle member 86 to thereb count the number of cups of coffee prepa It is believed that the operation of the entire device is clear from the above descrip- 18 tion. a

It is obvious that various changes and modifications may be made in the invention as disclosed above and it is the intention to claim all such changes and modifications as 20 will fall within the spirit of the following claim. I
